JP 2003-74247 A

  In the opening degree regulating device described in Patent Document 1, for example, when the window door is suddenly opened by wind pressure or the like in a state where the locking member of the main body portion of the frame member enters the recess of the hook member of the window door. However, there is a problem that the tip of the hook member may collide with the locking member with an excessive force, resulting in damage to the member such as the tip of the hook member or the locking member.

  An object of the present invention is to solve such inconveniences, and it is possible to control the opening of a shoji that can suppress the breakage of a member while being able to restrict the opening of the shoji and cancel the opening. The object is to provide an opening degree regulating device.

  The present invention solves the above inconvenience. That is, according to the present invention, an arm 8 is bridged between the window frame 2 and the shoji 3 in the open window 1 in which the shoji 3 is rotatably attached to the window frame 2 arranged in the opening of the building. An opening degree regulating device for regulating the opening degree of the shoji 3 by the arm 8, wherein one end of the arm 8 is swingably connected to one of the window frame 2 and the shoji 3. The shaft body 10 that fits in and out of the fitting hole 35 provided in the other end of the arm 8 is disposed on the other of the window frame 2 and the shoji 3. And a driving means 15 for moving the shaft body 10 between an advanced position where the shaft body 10 is fitted into the fitting hole 35 of the arm 8 and a retracted position where the shaft body 10 is removed from the fitting hole 35. To do.

  The casement window here includes a casement window, a casement window, a casement door, a casement door, and the like. The case where the shaft body 10 is supported so as to be movable with respect to the main body 7 attached to the window frame 2 or the shoji 3 is applicable. The drive means 15 includes a case where the mechanism is a solenoid or an actuator. The play (gap) between the shaft body 10 and the edge of the fitting hole 35 of the arm 8 may be large as long as the arm 8 can be easily swung. It is preferable that it is a play.

  Specifically, the drive unit 15 includes a motor 16, a cam 23 that is rotationally driven by the motor 16, and a biasing unit 24 that biases the shaft body 10 toward the advanced position. A part of the cam surface is recessed in the central axis direction to form a concave surface 36, and the upstream edge 36 a in the rotational direction of the cam 23 can contact the shaft body 10 on the advance position side on the concave surface 36. When the cam 23 rotates in the contact state, the shaft body 10 moves toward the retreat position side against the urging force of the urging means 24 by the edge 36a of the cam 23, and the arm 8 The fitting hole 35 is removed. Here, the case where the cam 23 directly contacts the shaft body 10 and the case where the cam 23 contacts the shaft body 10 indirectly by contacting a pin or the like provided on the shaft body 10 are included. The urging means 24 corresponds to a coil spring or a synthetic rubber.

  Moreover, it has the control part 20 which controls the motor 16 according to the signal from the emergency sensor 18 which senses an emergency, and when the control part 20 receives the signal from the emergency sensor 18, the motor 16 The shaft body 10 can be moved to the retracted position by actuating. The emergency sensor 18 detects an emergency such as a fire, a gas leak or an earthquake, and corresponds to a smoke sensor, a heat sensor, a gas sensor, an earthquake sensor, or the like. Moreover, the case where only one emergency detector 18 is arranged inside or outside the building and the case where a plurality of emergency detectors 18 are arranged are included. Here, the emergency sensor 18 and the control unit 20 communicate with each other by a wireless communication system or a wired communication system, and the control unit 20 transmits a signal from the emergency sensor 18 via the reception unit 21 including an infrared light receiver and an antenna. Is included.

  Moreover, it has the control part 20 which controls the motor 16 according to the signal from the remote control 19, and when the signal from the remote control 19 is received, the control part 20 operates the motor 16 and retracts the shaft body 10. It can be moved to a position. Here, the case where the remote controller 19 and the control unit 20 communicate by a wireless communication method or a wired communication method is applicable. When the remote controller 19 and the control unit 20 communicate with each other by a wired communication method, the remote controller 19 may be attached to an inner wall of a building. The case where the shaft body 10 can be moved to the advanced position by the operation of the remote controller 19 is also included.

  Further, the tip end surface 10c in the advancing direction of the shaft body 10 is inclined, and the other end portion of the arm 8 from which the shaft body 10 is detached can be brought into contact with the inclined tip surface 10c. By pushing the inclined tip end surface 10c of the shaft body 10 by the other end portion of the shaft 8, the shaft body 10 can move to the retracted position side against the biasing force of the biasing means 24. Here, the direction (posture) and shape of the inclined tip surface 10c of the shaft body 10 are set so that the other end of the arm 8 can abut even when the shoji 3 is fully closed or open. And the case where the tip end face 10c is curved is also included.

  Furthermore, it is possible to have means for manually moving the shaft body 10 to the retracted position side. For example, when the shaft body 10 is disposed in the main body 7 attached to the window frame 2 or the shoji 3, the hole provided in the main body 7 corresponds to the means for moving. In that case, a pin or the like is inserted from the hole and the shaft body 10 is manually moved to the retracted position side. In addition, for example, a case where a protrusion or the like as a means for moving the shaft body 10 is provided, and the shaft body 10 is moved to the retracted position side by grasping the protrusion with a finger or the like.

  In the case of the opening window opening regulating device of the present invention, during normal use, the shaft body 10 is in the advanced position and is fitted in the fitting hole 35 at the other end of the arm 8. As a result, the arm 8 is stretched over the window frame 2 and the shoji 3. In that state, the shoji 3 can only be opened up to a predetermined opening angle (for example, about 10 °) (opening restriction), so it is possible to open the shoji 3 for ventilation, but a suspicious person or the like opens. It cannot enter from the window 1.

  When the fire or the like occurs, the shaft body 10 is moved from the fitting hole 35 of the arm 8 by moving the shaft body 10 to the retracted position by the driving means 15 and the opening restriction of the shoji 3 by the arm 8 is released. . Thereby, the shoji 3 can be fully opened, for example, and can escape from the opening window 1 to the outdoor.

  As described above, during normal use, the shaft body 10 is fitted in the fitting hole 35 of the arm 8, so that the shaft body 10 and the arm 8 are securely connected. Therefore, for example, even if the shoji 3 is suddenly opened by the wind pressure and the arm 8 is pulled, the connection between the shaft body 10 and the arm 8 is disconnected, or the impact when the shaft body 10 or the arm 8 is suddenly opened is caused. It can be prevented from being damaged.

  The cam 23 is rotated by the motor 16 of the driving means 15, and the shaft body 10 is moved to the retracted position side against the urging force of the urging means 24 by the cam 23, so that the shaft body 10 is fitted into the fitting hole of the arm 8. By removing from 35, for example, the drive means 15 can be made more compact than the case where it is configured using an electromagnetic solenoid or the like that is larger than the motor.

  When the shaft body 10 is moved to the retracted position when the signal from the emergency sensor 18 is received, the shaft body 10 is automatically detached from the fitting hole 35 of the arm 8 in the event of an emergency such as a fire, The opening restriction of the shoji 3 by the arm 8 is released. Thereby, the shoji 3 can be fully opened immediately at the time of an emergency, and it can escape from the opening window 1 to the outdoor.

  When the shaft 10 is moved to the retracted position when the signal from the remote controller 19 is received, the opening restriction of the shoji 3 can be released in a state of being away from the opening window 1, so that the opening restriction of the present invention is accordingly increased. Usability of the device is improved.

  When the other end portion of the arm 8 from which the shaft body 10 is detached is brought into contact with the tip surface 10c of the shaft body 10 in which the advancement direction of the shaft body 10 is inclined, the tilted tip surface 10c is pushed. Since the body 10 moves toward the retracted position against the urging force of the urging means 24, the shaft body 10 can be moved without operating the driving means 15 by operating the remote controller 19 or the like to move the shaft body 10. The fitting hole 35 of the arm 8 can be fitted. The labor required when fitting the fitting hole 35 of the arm 8 to the shaft body 10 can be reduced accordingly.

  If the shaft body 10 is provided with means for manually moving the shaft body 10 to the retracted position side, the shaft body 10 can be moved even when the drive means 15 cannot move the shaft body 10 to the retracted position due to a failure or the like. Can be manually moved to the retracted position side to disengage the shaft body 10 from the fitting hole 35 of the arm 8 and open the shoji 3 to the fully open position. This also improves the usability of the opening degree regulating device of the present invention. .

A driving unit (driving means) 15 that is moved between a retracted position (a position shown in FIG. 6) that is removed (disengaged) from 35, a power source unit 17 that supplies power to the DC motor 16 of the driving unit 15, and smoke detection The control unit 20 performs control such as operating the DC motor 16 of the drive unit 15 when receiving a drive instruction signal transmitted from the emergency sensor 18 (FIG. 10) such as a detector or the remote controller 19 (FIG. 10). (FIG. 10) and a support member 22 for supporting the shaft body 10 so as to be movable in the vertical direction.

  The drive unit 15 includes the DC motor 16 arranged with its output shaft oriented sideways, a cam 23 connected to the output shaft of the DC motor 16 via a reduction gear and driven to rotate by the DC motor 16, A coil spring (biasing means) 24 that biases the shaft body 10 toward the advance position side (upper side in FIG. 2) is provided. The support member 22 has a vertically long support hole 26 into which the shaft body 10 and the coil spring 24 are fitted, a storage portion 27 (see FIG. 3) for storing the other end of the arm 8, a cam 23 and a limit switch 28. -The recessed part 30 which has arrange | positioned 29 is formed. As shown in FIG. 3, the accommodating portion 27 has openings on the outdoor and right side surfaces, and the other end of the arm 8 can be inserted into the accommodating portion 27 from the opening.

  As shown in FIG. 6, a fixing member 31 having an L-shaped cross section is attached to the bottom surface (lower surface) of the concave portion 30 of the support member 22, and the DC motor 16 is fixed to the fixing member 31. The left side of the recess 30 is open. A contact pin 32 extending toward the cam 23 is provided on the side surface (left side in FIG. 6) of the shaft body 10, and the contact pin 32 protrudes into the recess 30 on the back side surface of the recess 30. Therefore, a through hole 33 is formed (see FIG. 4). The through-hole 33 extends in the vertical direction.

  The support hole 26 of the support member 22 has a diameter of the upper portion 26a smaller than that of the lower portion 26b, and communicates the upper end side of the upper portion 26a with the accommodating portion 27. Further, the diameter of the upper part 10a of the shaft body 10 is made smaller than that of the lower part 10b. Thereby, when the upper part 10a of the shaft body 10 fitted in the support hole 26 by the urging force of the coil spring 24 protrudes into the accommodating part 27, the upper end of the lower part 10b of the shaft body 10 is the lower part 26b of the support hole 26. The upper end surface of the shaft body 10 is received (state of FIG. 2), and the upward movement of the shaft body 10 is restricted. The upper portion 26 a of the support hole 26 extends to the upper side of the accommodating portion 27, and the upper portion 10 a of the shaft body 10 projects to the upper side of the accommodating portion 27 at the advanced position. In addition, the lower part 10b of the shaft body 10 and the lower part 26b of the support hole 26 are rectangular in cross section, thereby preventing the shaft body 10 from rotating.

  By inserting (fitting) the upper portion 10 a of the shaft body 10 into the fitting hole 35 of the arm 8 with the other end of the arm 8 inserted into the accommodating portion 27 of the support member 22 of the main body 7, The other end is connected to the main body 7. In the connected state, the upper portion 10 a of the shaft body 10 does not come out of the fitting hole 35 of the arm 8.

  As shown in FIGS. 4 and 5, the cam 23 has a concave surface 36 formed by recessing a part of the cam surface in the direction of the central axis, and in the concave surface 36, the rotation direction of the cam 23 (in FIG. The edge 36a on the upstream side in the clockwise direction can be brought into contact with the contact pin 32 of the shaft body 10 (see the phantom diagram in FIG. 4). When the cam 23 further rotates in the contact state, the contact pin 32 is pushed downward by the edge 36a of the cam 23, and the shaft body 10 is pushed down against the biasing force of the coil spring 24 (FIG. 5). reference). In this state, the upper portion 10a of the shaft body 10 is detached from the fitting hole 35 of the arm 8 (state of FIG. 6), and the other end portion of the arm 8 can be taken out from the accommodating portion 27 of the support member 22.

  The contact pin 32 contacts the right half surface side of the cam surface of the cam 23. The operation levers 38 of the limit switches 28 and 29 are in contact with the left half surface side of the cam surface of the cam 23 (see FIGS. 4 and 5). Out of the cam surface of the cam 23, the outer peripheral surface 23a excluding the concave surface 36 is formed in an arc shape.

  As shown in FIG. 10, the remote controller 19 has a push button 19 a for transmitting a drive instruction signal for instructing to move the shaft body 10 downward (retracted position). The remote controller 19 is portable. One or more emergency detectors 18 are arranged inside or outside the building, and transmit a drive instruction signal when an emergency such as a fire is detected.

  The power supply unit 17 includes a primary battery or a secondary battery. When the power supply unit 17 includes a secondary battery, the control unit 20 includes a charge control circuit for charging the secondary battery, and also includes an overcurrent protection circuit as necessary. The emergency sensor 18 and the remote controller 19 and the control unit 20 communicate with each other by a wireless communication method using infrared rays, radio waves, ultrasonic waves, and the like, and accordingly, the main body 2 receives the drive instruction signal. It has the receiving part 21 (FIG. 10). The receiving unit 21 corresponds to an infrared light receiver, an antenna, an ultrasonic receiver, or the like.

  Note that the emergency detector 18 and the remote controller 19 and the control unit 20 may communicate with each other by the radio while the remote sensor 19 and the control unit 20 communicate with each other by infrared rays. In this case, the receiving unit 21 has an infrared receiver and an antenna. Further, the emergency sensor 18, the remote controller 19 and the control unit 20 may communicate with each other using infrared rays, and the emergency sensor 18, the remote control 19 and the control unit 20 may communicate with each other by radio waves.

  The first limit switch 28 of the main body 7 is configured such that, as the cam 23 rotates, the contact pin 32 of the shaft body 10 is pushed down to the lower end position by the edge 36a of the concave surface 36 of the cam 23. It turns on in a state where the cam 23 is removed from the concave surface 36 and is in contact with the outer peripheral surface 23a of the cam 23 (the state of FIG. 5). The contact pin 32 is held at the lower end position while contacting the outer peripheral surface 23 a of the cam 23. Further, the first limit switch 28 is turned off when the abutment pin 32 comes off the cam surface of the cam 23 as the cam 23 rotates and returns to the upper end position by the biasing force of the coil spring 24 (FIG. 4). State). The second limit switch 29 is turned on only while the tip of the operation lever 38 is in contact with the outer peripheral surface 23 a of the cam 23. When the second limit switch 29 is on, the first limit switch 28 is off. The control unit 20 operates and stops the operation of the DC motor 16 of the drive unit 15 based on the on / off of the limit switches 28 and 29.

  When receiving the drive instruction signal, the control unit 20 operates the DC motor 16 to lower the shaft body 10. Thereby, the shaft body 10 can be detached from the fitting hole 35 of the arm 8, and the other end portion of the arm 8 can be detached from the main body 7. When a predetermined time (for example, 30 seconds) elapses from the lowering of the shaft body 10, the control unit 20 operates the DC motor 16 to raise the shaft body 10.

  As shown in FIGS. 7 to 9, the upper portion 10a of the shaft body 10 has a tip surface (upper end surface) 10c in the advancing direction (upward in FIG. 7) inclined, and the inclined tip surface 10c is inclined to the inclined tip surface 10c. The other end portion of the arm 8 from which the shaft body 10 has been detached can come into contact. Specifically, the tip surface 10c of the upper portion 10a of the shaft body 10 is inclined downward toward the outside of the main body 7 and inclined toward the outdoor side.

  For example, when the shoji 3 is closed (fully closed) and the other end of the arm 8 removed from the main body 7 is inserted into the accommodating portion 27 of the main body 7, the other end of the arm 8 is inclined to the shaft body 10. 8 is in contact with the distal end surface 10c (state shown in FIGS. 8 and 9). When the other end portion of the arm 8 is further pushed into the housing portion 27 of the main body 7, the inclined end surface 10 c of the shaft body 10 is retracted against the biasing force of the coil spring 24 by the other end portion of the arm 8. Is pushed down (the state of the phantom diagram of FIG. 7).

  When the other end portion of the arm 8 is pushed all the way into the housing portion 27 of the main body 7 shown in FIG. 3, the inclined tip surface 10 c of the shaft body 10 enters the fitting hole 35 of the arm 8, and the shaft body 10 rises and fits into the fitting hole 35 of the arm 8. The other end of the arm 8 detached from the main body 7 in a state in which the shoji 3 is opened (for example, in the state of the phantom diagram of FIG. 1) because the front end surface 10 c of the shaft body 10 is inclined to the outdoor side. Even if the portion is inserted into the housing portion 27 of the main body 7, the other end portion of the arm 8 can be brought into contact with the inclined tip surface 10 c of the shaft body 10 as shown in a virtual diagram of FIG. 8. Thereby, the shaft body 10 can be pushed down at the other end of the arm 8 as described above.

  In this way, the fitting hole 35 of the arm 8 can be fitted into the shaft body 10 simply by pushing the other end of the arm 8 into the accommodating portion 27 of the main body 7. It is not necessary to perform the operation of lowering and raising the body 10, and it is possible to reduce time and labor when fitting the fitting hole 35 of the arm 8 to the shaft body 10.

  Further, a guide hole 40 as a means for manually moving the shaft body 10 to the retracted position side is formed from the upper end surface of the support hole 26 of the support member 22 to the upper surface of the main body 7. Then, in a state where the upper part 10a of the shaft body 10 is inserted into the fitting hole 35 of the arm 8 and the arm 8 is connected to the main body 7, a pin or the like is inserted from the upper end opening of the guide hole 40, and the shaft is By pushing down the body 10 against the urging force of the coil spring 24, the shaft body 10 can be removed (removed) from the fitting hole 35 of the arm 8.

  As a result, even if the remote controller 19 is operated due to a battery exhaustion or a failure of the main body 7, the DC motor 16 of the drive unit 15 does not operate, and the shaft body 10 remains fitted in the fitting hole 35 of the arm 8. Alternatively, the shaft body 10 can be removed (removed) from the fitting hole 35 of the arm 8 using the pin or the like.

  Next, operation | movement of the opening degree control apparatus of this invention is demonstrated. In the state of normal use, the opening window 1 according to the present invention has the shaft body 10 of the main body 7 fitted in the fitting hole 35 of the arm 8 and the other end of the arm 8 is connected to the main body 7. Thereby, the shoji 3 can be opened only to the predetermined opening angle.

  In this state, for example, when the push button 19 a of the remote controller 19 is pressed and a drive instruction signal is transmitted from the remote controller 19, and the receiving unit 21 of the main body 7 receives the drive instruction signal, the control unit 20 performs direct current of the drive unit 15. The shaft 16 is lowered by operating the motor 16. As a result, the shaft body 10 of the main body 7 is detached from the fitting hole 35 at the other end of the arm 8 so that the shoji 3 can be fully opened (for example, 90 ° or more).

  Further, when the driving instruction signal is transmitted from the emergency detector 18 due to the occurrence of a fire or the like, and the control unit 20 receives the driving instruction signal via the receiving unit 21, the DC motor 16 is driven and the shaft body 10 is driven. Descends. As a result, the shaft body 10 of the main body 7 is removed from the fitting hole 35 at the other end of the arm 8, and for example, the shoji 3 can be fully opened and escaped from the opening window 1 to the outside.

  When a predetermined time has elapsed from the lowering of the shaft body 10, the shaft body 10 is raised, and when returning to the normal use state after that, the other end portion of the arm 8 from which the shaft body 10 has been detached is attached. It inserts in the accommodating part 27 of the main body 7, and pushes the inclined front end surface 10c of the shaft body 10. FIG. As a result, the shaft body 10 is lowered, and the shaft body 10 can be fitted into the fitting hole 35 of the arm 8.

  The control unit 20 operates only every predetermined time (for example, several seconds), and the remote controller 19 transmits a drive instruction signal for a time longer than the operation stop time of the control unit 20. The control unit 20 operates the DC motor 16 of the drive unit 15 when receiving the drive instruction signal within the operation time. Thus, the power consumption of the opening degree regulating device can be suppressed by operating the control unit 20 only every predetermined time.

  A commercial power supply may be used as the power supply. In this case, an AC motor is used instead of the DC motor 16. When the commercial power source is used, the commercial power source may be rectified and supplied to the DC motor 16 or the like. The remote controller 19 and the control unit 20 may communicate using a wired communication method. Similarly, the emergency detector 18 and the control unit 20 may communicate using a wired communication method.

  In addition to the smoke sensor, the emergency sensor 18 includes a heat sensor, a gas sensor, and an earthquake sensor. Further, when the opening degree regulating devices are respectively installed in the plurality of opening windows 1, the opening degree regulating devices can be operated simultaneously by the drive instruction signals transmitted from one or a plurality of emergency detectors 18. . Further, for example, one or a plurality of emergency detectors 18 are connected to a control panel (not shown) by wire or wirelessly, and a drive instruction signal is transmitted from the control panel to each opening degree regulating device by wire or wirelessly. May be.

  Thus, in the opening degree regulating device of the present invention, during normal use, the shaft body 10 of the main body 7 is in the advanced position and is fitted in the fitting hole 35 of the arm 8. As a result, the arm 8 is stretched over the window frame 2 and the shoji 3. In that state, the shoji 3 can only be opened up to a predetermined opening angle (for example, about 10 °) (opening restriction), so it is possible to open the shoji 3 for ventilation, but a suspicious person or the like opens. It cannot enter from the window 1.

  By moving the shaft body 10 to the retracted position when a fire or the like occurs, the shaft body 10 of the main body 7 is released from the fitting hole 35 of the arm 8, and the opening degree restriction of the shoji 3 by the arm 8 is released. As a result, the shoji 3 can be fully opened to escape from the opening window 1 to the outside.

  As described above, during normal use, the shaft body 10 of the main body 7 is fitted in the fitting hole 35 of the arm 8, so that the shaft body 10 of the main body 7 and the arm 8 are securely connected. In other words, for example, even if the shoji 3 is suddenly opened by the wind pressure and the arm 8 is pulled, the connection between the shaft body 10 and the arm 8 may be disconnected, or the shaft body 10 or the arm 8 may be damaged. It can be suppressed.

  In the above description, the connecting member 9 is attached to the saddle 4 of the shoji 3 and the main body 7 is attached to the window frame 2. However, the connecting member 9 is attached to the window frame 2 and the main body 7 is attached to the saddle 4 of the shoji 3. 8 may be connected to the connecting member 9 of the window frame 2 and the fitting hole 35 of the other end of the arm 8 may be fitted (connected) to the shaft body 10 of the main body 7 of the shoji 3. Further, the remote controller 19 has a push button for transmitting a signal instructing to move the shaft body 10 upward (advance position), and when the control unit 20 receives the signal, the shaft body 10 is advanced. You may make it move to a position.
